CREEP at the Geothermal Volcanology Workshop 2018 (September 2018, Petropavlovsk-Kamchatsky, Russia)

Kamchatka is an active volcanic, seismic and hydrothermal region. Active volcanism is accompanied by magma injections into host structures, magmatic fracturing and the formation of hydrothermal systems adjacent to volcanoes. Engineering study of productive geothermal reservoirs is a necessary condition for their effective use for heat and power supply. Geomechanical analysis of the magmatic fracturing regime with seismic data is extremely important for predicting volcanic activity. It is also useful for analyzing the productivity of geothermal reservoirs and as the analog of hydrocarbon reservoirs development with hard-to-recover reserves. The interdisciplinary focus of this workshop bring together scientists to solve problems which transcend the framework of international borders.

CREEP at 2nd International Geothermal Conference GEOHEAT (September 2018, Petropavlovsk-Kamchatsky, Russia)

The event contribute to the solution of a number of fundamental problems: the development of theoretical issues of geothermics and heat flow of the Earth; establishment of new features of thermophysical processes in the geothermal water field development with supercritical thermo- dynamic parameters; the establishment of geothermal parameters of the Earth crust on basis of advanced experimental technologies (continuous thermal core logging technology, instruments for thermal property measurements at formation conditions, accounting of rocks heterogeneity, as well as micro- and macroanisotropy), and on this basis the geothermal resources revaluation, including geothermal resources maps.
